Application filed September 11, 1914. Serial No. 861,225.

Be it known that 1, JOHN BRICKEN, a sub ject of Russia, residing atChicago, in the county of Cook and State of Illinois, have invented acertain new and useful Improvement in Machines for Making Bows, of whichthe following is a full, clear, concise, and exact description.

My invention relates to a machine for tyingbow-knots, and moreparticularly to a machine for forming a continuous ribbon into aplurality of bows.

The object of the invention is to provide a machine of the characterdescribed which will do the work which has heretofore been commonly doneby hand, and which will produce bows much more rapidly than hasheretofore been possible. further object is to provide a machine whichwill form. bows of uniform size and best possible shape.

My invention consists primarily in a novel combination of groups ofelements, practically all of which groups constitute novelsub-combinations of the main invention.

One feature of my invention, therefore, relates to a broad combinationof mechanisms for tying a bow-knot.

Another feature relates to the ribbonguide which moves from side to sideof the machine to extend the ribbon.

Another feature relates to the fingers which grasp the extended ribbonat a point distant from the end of the ribbon and over which the ribbonis folded to form one of the loops of the bow.

Another feature relates to the reciprocating jaws which grasp .theextended ribbon and fold it back over one of the said fingers in formingthe bow loop.

Another, feature relates to the mechanism for severing the ribbon intolengths suitable for bows.

Another feature relates to the knot-forming jaws.

Another feature relates to the knot-guide which. serves to holdv openthe temporary loop .while the second bow-loop is drawn therethrough andthen to properly position the knot formed by tightening the-loop.

Another feature relates to the oscillatory jaws which carry the ribbonabout the bowloop first formed and present it to the knotforming jaws.

The above named and other features of my invention and their cooperationwith one another may be more readily understood by reference to theaccompanying drawings of a machine embodying the invention, in whichFigure 1 is a front elevation;

Fig. 2 is a rear elevation;

Figs. 15 to 21-inclusive are detail perspective views showing successivesteps in the operation of the machine; and

Fig. 22 is a perspective view of a bow formed by the machine.

Like letters of reference refer to like parts throughout the severalviews of the drawlngs.

The main shaft, -1 of the machine can be driven from any suitable sourceof power. The drawings show a manually operated handle 2 (see Figs. 1and 3) which,through the medium of a pinion 3, drives a gear wheel 4secured upon the shaft 1. The shaft i 1 is journaled at one end in thefront frame plate 5 and passes through an opening in the plate 6, beingjournaled at the other. end in a short plate or bearing block 7.

At its rear the shaft 1 has secured thereto a crank arm 8 (see Fig. 2)which is connected by a curved connecting rod 9 with a crank arm 10secured upon a crank shaft 11. Said crank shaft also has secured theretoan oscillating arm 12 (see also Figs.

3 and 5), having upon its upper end a head w vill now bedescribed,reference being made 13 to which is rigidly secured a sleeve 14.Inclosed within the'sleeve 14-is a shaft 15, having upon its forward orfree end a ribbon-guide 16. Said ribbon-guide may be in the form of arectangle (see Fig. 4) having a guide roll 17 journaled in its upper endover which the ribbon passes down between a pair of guide rolls 18journaled 1n the lower end'of the rectangle.

The ribbon, braid or other material 25 from which the bows are formed isled from a rotatably mounted spool 19 (see Fig. 2) about alongitudinally extending rod 20 at the front of the spool and fromthence above the spool and about another rod 21 located at the rearof'the spool parallel to the rod 20. From thence the ribbon is ledthrough a loop 22 to the ribbon-guide 16. A weight in the form of a ring22 through which the ribbon is threaded is employed to provide theproper tension upon the ribbon.

It will thus be seen that as the main shaft 1 is. driven, in the presentcase in a clockwise direction by the contra-clockwise rota tion of thehandle 2, the oscillating arm 12 is reciprocated from left to right (seeFig. 5) to feed the ribbon in the manner to be presently described.

For the purpose of maintaining the ribbon-guide 16 in a verticalposition, a system of parallel links may be employed, said systemcomprising a link 23 (see Fig. 2) pivoted in the frame of the machineand con nected at its upper end with a link 24 pivoted at one end of thelink 23 and rigidly secured at its other end to the shaft 15. Suchsystem of parallel links maintains the ribbon-guide 16 in its verticalposition.

Referring more particularly to Fig. 3, the machine is shown in positionready to begin the operation of forming a bow from the ribbon. The outerend of the ribbon 25 at this time is held by a clamping finger 26 whichholds the end of the ribbon in a groove in the knife blade 27 and whichis parallel to the cutting edge of the blade, (see also Fig. 12), saidribbon extending between two upstanding guides 28. As the ribbon-guide16 is reciprocated from left to right in the manner heretoforedescribed,

the'ribbon is extended lengthwise of the ma-' chine between a pair ofupstanding guides 29 and above the end of a stationary finger 30 whichextends forward from a downward projection of .a support 31 secured tothe frame-work of the machine (see Figs. 3 and 6).

Just prior to the positioning of the rib.

bon in the manner just described, a pair of reciprocating gripping jaws32,33 open up to receive the ribbon between the same, said gripping jawsbeing at the same time slightly elevated (see Fig. 15). The mechanismfor reciprocating these gripping jaws from a cam 39. The cam 39 issecured upon a shaft 40 which is adapted to be driven, through a systemof gears 41, 42, 43, from the gear wheel 4 of the main driving shaft(see Fig. 1). Said cam 39 operates upon a lever 44 pivoted at 45upon-the frame work of the machine and having a roller 46, which bearsupon a surface of the cam 39. The other end of the lever 44 is connectedby a link 47 with a crank arm48 of the shaft 38.

Thus, as the lever 44 is raised and lowered by the surface of the cam39, the shaft 38 is rocked to oscillate the arm 37 from left to rightand thereby to reciprocate the sleeve '34 and the grippingjaws carriedthereby. The function of the/reciprocation of the and opened asshown inFig. 15. The lifting of the jaws is controlled by a cam 49 (see Fig. 6)mounted upon the shaft 40. The cam 49 operates through a roller 50 upona lever 51, one end of which is loosely mounted upon the shaft 38 andthe other end of which is normally held up by a spring 52. Pivoted uponthelever 51 is a link 53 which at its upper end is pivoted to a crankarm 54 carried by the shaft 35. In this manner the cam 49 acts to permitthe spring 52 to draw. 'up the arm 51 to a slight extent and thusslightly lift the jaws 32, 33.

I The mechanism for opening and closing the jaws 32, 33 will now bedescribed, reference being had more particularly to Figs. 3, 5, 6, 8, 9and 10. The jaw 33 is secured upon the end of a pin 55, which is journaled in the sleeve 34. At its other end the pin 55 is provided witha crank-arm 56, which is normally held in a lowered position by aspring57, thus normally holding the .jaw

33 closed with respect to the jaw 32. Atv

the end of the movement of the jaws to the thereof engages the crank-arm56 and rocks the pin 55, thereby opening up the jaw 33. Immediatelyafter the ribbon is thus located between the jaws 32 and 33, the cam 58is moved to a position to permit the spring 57 to close the aw 33.

At the same time that the gripping jaws 32, 33 are operating to receiveand grip the ribbon, a movable pivoted finger 61 is being moved downwardto clamp the ribbon against the finger 30 (see 16). Referring moreparticularly to Figs. 3, 5, 6, 10 and 11, it will be seen that themovable finger 61 is adapted to be actuated through the medium of a cam62 mounted upon the shaft 59 (see particularly Fig. 11). The cam 62 actsupon a bell-crank lever 63, the opposite end of which is connected by alink 64 with a been heretofore fully described. The

crank-arm 65 of a rockshaft 66, upon which is secured the arm of theclamp 61. The cam mechanism is so timed that the finger 61 is lifted andthus moved outof the way as the ribbon is extended longitudinally of themachine. As the ribbon comes in position'above the finger 30 thecoiiperating finger 61 is brought down to hold the ribbon.

The next step in the operation of the machine is the release of the endof the ribbon from the clamping jaw 26, in order to permit said end tobe folded back over the finger 30 (see Fig. 17) by the reciprocation ofthe gripping jaws 32, 33 to form one loop of the how. This releasing ofthe end of the ribbon will now be described. Referring more particularlyto Figs. 4, 6, 11, 12 and .13, it will be seen that the knife-blade 27,in the groove of which the ribbon is clamped by the clamping jaw 26, iscarried upon a projection of a lever 67. Said lever is normally held ina lifted position by a spring 68, but is adapted to be depressed by acam 69 secured upon the shaft At the point of the operation of themachine just described, the cam 69 acts to depress the lower end of thelever 67 against the tension of the spring 68 and thus to slightly lowerthe knife blade 27, thereby releasing the end of the ribbon.

The operation of the gripping jaws 32, 33 to fold the ribbon back uponitself to form one of the loops of the bow will now be described.Although the jaws 32,33 are grasping the ribbon, the jaws are merelyclosed under spring tension which permits downward a slight extent underthe action of the cam 49, the operation of which has P' ping jaws arethen moved to the right under the action of the cam 39, the operation ofwhich has also been fully described.

At the same time that the gripping jaws 32, 33 are moved to the right toform one of the loops of the how, the ribbon-guide 16 is oscillated tothe left in the manner hereinreference being had more particularly toFigs. 1, 3, 5, 6, 7, 8 and 11. At the time in the hereinbefore describedoperation of the machine when the gripping jaws 32,. 33 are opened up toreceive the ribbon, and the ribbon is extended lengthwise of themachine,- the jaws 70 and 71 of the knot-forming mechanism are moved tothe rear and directly above the extended ribbon. The jaw 71 is integralwith a sleeve 72, which is secured upon the outer end of a lever arm 73.The lever arm 73 is pivoted intermediate of its ends upon a crank-arm 74secured upon the end of a rock shaft 75. The rock shaft 75 acts toreciprocate the lever 73 from right to left, such movement of the rockshaft being controlled by a cam 76 secured upon the shaft 59. Said camrocks the shaft 75 through a system of levers 77, 78, and 79. Inaddition to being moved to the left in the manner just described, thearm 73 is adapted to be swung to the rear so as to bring theknot-forming jaws above the extended ribbon. For this purpose, the endof the lever 73 is pivotally connected through a link 80 and a crank-arm8'1 with a rock shaft 82. The rock shaft 82 is arranged to be actuatedby a cam 83 carried by the cam shaft 40 (see Figs. 6 and 11). The cam83, through the medium of a roller 84, acts upon a lever 85, to theupper end of which is connected a link 86, thereby reciprocating saidlink, which in turn, through a crank-arm 87, rocks the shaft 82. Thejaws 70 and 71 of the knotting mechanism are thus moved into place abovethe extended ribbon (see Fig. 17). Therefore, when the ribbon-guide 16moves to the left, as heretofore described, the ribbon is doubled backover the jaws 70, 71 to form a temporary loop (see Figs. 19 and 20)through which the other loop of the bow is-to be subsequently drawn,said temporary loop being drawn into a knot after the last mentionedbow-loop is formed (see Fig. 21).

As the ribbon is folded back over the temporary loop-forming aws 7 O,71, the ribbonclamp 61 is actuated by its cam and is moved upward out ofthe path of the ribbon. The mechanism for operating this ribbon-clamphas been hereinbefore described. At the same time that the clamp 61 ismoved out of the path of the ribbon, the clampingfinger 26 and one blade89 of the cutting mechanism are moved to the rear to permit the ribbonto be brought into position to be cut by the knife. Referring to Figs.11 and 12, the clamping-finger 26 is mounted upon the upper end of alever 90, on which is also secured the blade 89,'said finger extendingparallel with said blade in position to enter the groove in thecooperating blade 27 when said blades are closed together. The lever 90is pivoted intermediate of its ends upon the frame of the machine and isadapted to be actuated by a cam 91 secured upon the cam shaft 59. Afterthe ribbon has been extended across the knife blade 27, the knife blade89 is moved back into position to cooperate with the blade 27. Thereuponthe knife blade 27 is lifted to a slight extent, as heretobeforedescribed in connection with Fig. 13, thereby cutting off a length ofribbon required for the bow that is being formed and simultaneouslyclamping the end of the ribbon preparatory to the operation of formingthe next succeeding bow (seev Fig. 18)

rior to the severing of the ribbonand as the ribbon is brought down inposition upon the knife blade 27, the ribbon is grasped at a pointbetween the finger 30 and the blade 27 by a pair of oscillatory jaws 92,93 (see particularly Figs. 14 and 18). The jaw 92 is in the form of apin which extends forward from a head 94 secured to a sleeve 95. The jaw93 is in the form of a pin parallel to the jaw.92. The jaw 93 is pivotedupon the head 94 and a spring 96 tends to hold the two jaws in closedposition. The sleeve 95 has secured thereto a pinion 97 which mesheswith a segmental rack 98. Said rack turns the pinion 97 to oscillate thejaws through almost a complete revolution. The segmental rack 98 is uponthe upper end of a lever 99, which is pivoted at its lower end and whichis acted upon by a cam 100 Secured upon the shaft 40. The cam 100 servesto oscillate the segmental rack 98 from left to right and thus to turnthe pinion-first in one direction for almost a complete revolution andthen in the opposite direction. After the ribbon has been drawn backover the jaws ,70 and 71, the oscillatory jaws 92, 93, which at thattime are separated from each other, are moved forward, one of the jawsbeing thus brought above and the other below the ribbon. In order thatthe jaws 92 and 93 may be this moved forward, the sleeve 95 isslidablymounted upon a supporting pivot 101. A sleeve 102 surrounds the sleeve95 and has projecting therefrom a pin 103 to which is pivoted the upperend of an operating lever 104. The lever 104 is secured at its lower endupon a short-rock shaft 105 which extends longitudinally of the machine.The rock-shaft 105 is adapted to be actuated by a cam 106 secured u on vthe cam shaft 59 (see Figs. 5 and 10). he cam 106 controls the actuationof a crankarm 107 secured upon the rock-shaft 105. Therefore as theribbon is\brou 'ht in place to be severed by the cuItting me hanism thejaws 92 and 93 are moved forward upon opposite sides of the ribbon. Saidjaws are then closed through the action of a cam 108 secured upon thesleeve 102 (see Fig. 18). As the sleeve 95 and the crank-arm 94 thereofare turned by the pinion 97, a roller 109 carried by the pivoted jaw 93engages with the cam 108. Said cam thus controls the opening and closingof the jaw 93, and at the proper time the cam permits the spring 96 toclose the jaw 93 upon the jaw 92 and thus to hold the end of the lengthof ribbon from which the bow is formed.

In the next succeeding step in the operation of the machine, theoscillatory jaws 92, 93 are moved forward and then downward and rearwardthus carrying the severed end of the length about the bow-loop alreadyformed (see Fig. 19). The ribbon as it is brought aroundsaid bow-loop isguided by a curved finger 109 which rojects beyond the end of the sleeve34. Said finger 109 is mounted to reciprocate with the jaws 32, 33 andis therefore moved to its operative position when said jaws are at theend of their stroke to the right. The downward and rearward movement ofthe oscillatory jaws are controlled by the cams 100 and 106,respectively, in the manner already described. When said jaws havecarried the end of the severed material below the finger 30, the clamp61 is operated by its cam to hold in place the bow-loo previously formedabout the finger 30. ear the completion of the oscillation of the jaws92, 93, the length of ribbon is carried thereby between the jaws L 70,71, (see Fig. 19) which latter jaws have moved to the left to locate theposition of the temporary loop and have opened up to adjust the lengthof such temporary loop. When the oscillating jaws 92 and 93 have movedup to their highest position the jaw 70 is closed upon the jaw 71.

Just previous to the closing of the jaws 70 i and 71 upon thesevered'length, a knot-locating guide 110 (see Figs. 3, 15, 16 and 17)is swung forward into the temporary loop.

Said knot-locating guide has an angular V which through a link serves torock the shaft 112, and thus actuate the guide 110.

When the knot-locating guide has thus been swung into the temporary loopthe jaw 70 closes upon the jaw 71 and the end of the piece of ribbon isgrasped between said jaws.

The means for closing the jaw 70 upon the j aw, 71 hereinbeforementioned will now be described. The jaw 70 is secured upon the 19 and21).

lower end of a pin 116, which extends through the sleeve 72 (see Figs.3, 6 and 10). The upper end of the pin 116 has secured thereto acrank117, which is connected by a .and 71 is controlled by the rock-shafts 82and 120, such shafts being operated by their cams in the mannerhereinbeforecdescribed. The ribbon is thus drawn through the temporaryloop and doubled back upon itself to form one of the loops of the bow(see Figs. Meanwhile one end of the length of ribbon is being heldbetween the jaws 32 and 33. The knot-locating guide,

which has served to hold the temporary loop open while the loop of thebow is drawn therethrough, is during this operation gradually withdrawnfrom the temporary loop,

which is thereupon permitted to be drawn into a knot by the pullingaction of the jaws 70, 71. Theguide 110 as it is withdrawn also servesto properly locate the position of the knot.

When the knot has thus been tied and the bow therefore completed, thejaws 32, 33 are slightly opened up to release the end of the bow thathas been held thereby while the lmot was being tied. This opening ofsaid jaws is accomplished by the action of a cam 131 upon a lever 132(see Fig. 8). The lever 132'actuates the crank 56 to open up the jaws insubstantially the same manner as the jaws are opened up by the opera-,tion of the lever 60 hereinbefore described in connection with Fig. 9.

After the jaws 32, 33 have thus opened up to release the end of the bow,the cams 121 and 76 permit the jaws 70, 71 to open and thereby releasethe loop of the bow from said jaws. At the same time the clamp 61 isoperated by its cam to release the other loop of the bow from the finger30. Thereupon a kicker arm 124 is moved downward to eject the formed bowfrom the machine. The kicker or ejecting mechanism consists of a kickerarm 124, having on its free end two downwardly extending prongs 125 (seeFigs. 3 and 4). The kicker arm is normally in an elevated position butis adapted to be lowered through the medium of a crank arm 126 securedto a rockshaft 127. Said rock shaft extends transversely of the machineand at its forward end is provided with a crank arm 128 which is springpressed against the surface of a cam 129 secured to the gear wheel 4(see Fig. 1). Thus, at the proper time in the operation of the machine,said kicker arm is depressed and the bow is pushed by the prongs 125into a. chute 130 which guides the completed bow from the machine.

The grippin 'aws 32, 33 upon the completion of the i i ieration thus fardescribed are moved to the left preparatory to forming another bow, suchmovement being under the control of the cam 39, as hereinbeforedescribed.

During the foregoing described operation of forming one bow from thesevered length of ribbon, the oscillating ribbon guide 16,

after theribbon has been severed, moves to the right, in the mannerhereinbefore described, for the purpose of extending the .ribbon for thenext succeeding bow. -At the same time the oscillatory jaws 92, 93- arereturned to their initial position and opened preparatory to graspingthe ribbon when it has been extended above the finger 30. The operationsof forming two successive bows, thus, to a certain extent, overlap eachother.

The various cam shafts hereinbefore described are all operated from themain drivcut that such details may be widely varied without departingfrom the spirit and'scope of the invention as set forth in theaccompanying claims.
